Error in unwrraping

When process unwrraping in bkack window in red line type ABROT.
What is mean?

“abort” means it has failed, it can have many reasons. Has it worked before with different data or is this your first try?

Have you selected a suitable number of tiles and pixel overlap?

Hi
It is my first try for determin landsubsidence.
I selected row overlap and colum overlap 200.
Is it true?

there is no true or false, but a bit of an overlap helps to merge the tiles correctly together.
How large is your raster? (rows colums)

Dear mr/mis abraun
When we use snap in unit data in oder trying ,the result is defferent. but this results arenot resonable.
What is deal?

Sorry, I don’t understand.
Maybe you can clarify with a screenshot.
